if LE audio can support multiple audio source and sink at the same time

[chen_jackcw]

I have one question about LE audio.

If it can support multiple audio sources and sinks, each source can unicast its stream to dedicated sink.

for example. 3 smartphones and 3 earphones, audio stream from phone 1 is to earphone 1, phone 2 is to earphone 2, phone 3 is to earphone 3.

Everyone can hear their own audio

Hello,

Could you please clarify if you are using any NXP product?

Or are you interesting in any recommendation?

Hi Ricardo,

We are planning the car head unit proposal to customer, because the requirement is the head unit could have 5 or 6 device connections at the same time and our proposal is as the picture.

The head unit in car can have at most 5 or 6 connections with devices including phone, headphone etc. and each passenger represent by different color can use his phone to stream the media to his headphone.

We need to get some infomation to prepare the head unit proposal to our customer.

Thanks

Jack

Hello, Good Day!

I would suggest having a look at the NXH3675 chip, which is a dedicated BLE Audio Solution that would be feasible for the mentioned application, given it includes a radio BLE subsystem with support for up to 8 ACL, scan and/or advertisement channels. With this, you would be able to include up to 4 audio sources (phones) and 4 audio sinks (headphones) at the same time.

If you are planning to acquire this chip, please consider that we offer an NXH3675SDK Evaluation Kit for exploring all the available features, along with an SDK that includes code example applications.

Please consider as well that the mentioned SDK, the complementary tools, support and documentation of the NXH3675 are available for selected customers with an approved NDA.

Regards,
Ricardo
